JEAN ADAM G-EOEG IFFEBT, OF FRANKFORT ON-TI EsMAIl T, GERMANY, ASSIGNOR T0 UNITED SHOE MACHINERY COMPANY, OF PATEB'SQN, NEW JERSEY, A. CORPORA- TION OF NEW JERSEY.

To (all whom it 'nmg concern:

Be it known that 1, Juan ADAM Gnono Irrnnr, a subject of the King of Prussia, residing at Frankfort-on-the-Main, in the Kingdom of Prussia, Germany, have invented certain Improvements in Pulling-Over Machines, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to apparatus for use in making shoes and particularly to pulling-over machines and has for its object to improve tip measuring devices of pullingover machines.

Tip measuring devices as heretofore constructed for pulling-over machines have been of two types, one of which included measuring devices extending along the side or sides of the shoe and indicating the position of the end portions of the tip seam. The other type included a device extending along the middle portion of the shoe and indicating the position of the tip seam on the top face of the shoe. Inasmuch as the top face of the shoe is the portion most conspicuous on the wearers foot it will readily be seen that the latter type has an advantage. It has a disadvantage, however, in that, as heretofore constructed, the measuring device hides the middle portion of the toe and therefore interferes with that convenient inspection of the work during the tip measuring process which is desirable for the best results.

An object of the present invention is to overcome this disadvantage in that type of tip measuring devices which indicates the position of the tip seam over the top face of the last.

The several features of the invention will be apparent from the following description of an illustrated embodiment thereof and will be pointed out in the claims.

Figure 1 is a front elevation of so much of a pulling-over machine, equipped with the present invention, as is necessary for an understanding of the invention. Fig. 2 is a side elevation.

The pulling-over machine illustrated is one of that type represented by the McFeely United States Letters Patent 663,7 7 7 granted Dec. 11, 1900, and comprises toe and side grippers 1 and 2 which are operated for seizing and stretching the forepart of the Specification of Letters Patent.

upper and then come to rest to permit the operator to inspect the shoe and ascertain if the various lines of upper, of which the tip seam line is one of the most conspicuous, are located in proper relation to the last.

If these lines are found not to be so located,

adjustments are made for re-positionin the upper by the means provided in themac ine, asexplained in said patent. The tip measuring device is carried by parallel links 6 which are pivoted at 8 to the rearwardly projecting end portions of a bracket 10 which is fastened at 12 to the front face of the machine frame. From points at the end of the bracket near the fastening, the tensioned springs 14: extend to the front end portions of the links 6 and normally up hold the links and measuring device against a stop 15 as shown in dotted lines in Fig. 2, while permitting the measuring device to be moved into operative position, shown in full lines in said figure and in Fig. 1. The lower ends of the links 6 are connected by a bar 16, one end of which extends beyond the links to form a handle 7 and upon the lower rear face of this bar a toe abutment plate 20 is clamped in adjusted position by a binding screw 22 and is adapted for engagement with the end face of the shoe as shown in Fig. 2. On the front face of the bar 16 and extending at right angles to the abutment plate 20 is located the measuring plate 25, said plate being adjustable lengthwise by means of the screw 24 which is threaded into the bar 16. This measuring plate is located at one lateral side of the abutment plate as clearly shown in Fig. 1 where it offers a minimum of obstruction to the operators view of the shoe. The measuring plate is marked with a graduated scale and a pointer 28 on the bar 16 cooperates with the scale to indicate the correct measurements for the toe tips. The measuring plate does not extend in a direct line to the toe tip but instead carries a sickle-shaped plate 26 which extends from the plate 25 outwardly from the median line of the shoe and rearwardly curves around to a point substantially in the median line of the machine where it may engage the rear edge of the tip seam. By reason of this formation of the plate 26 the greater portion of the length of the tip seam is exposed to the unobstructed view of the operator so that he may see whether or not the tip seam is bowed or improperly curved and may watch the effect of the operation of the tip straightening devices of the pulling-over machine in correcting an improperly positioned tip seam.

The bar 16 which carries the toe abutment and the measuring plates 25, 26 is mounted to have a limited turning movement about its own axis in the links 6 and is held by a spring 30 in a position in which the toe abutment plate 20 bears against a stop 32, Fig. 2. The plates are so arranged that when the measuring device is swung down to its operative position the plate 26 first contacts with the shoe and the bar 16 turns slightly against the pull of the spring until the toe abutment plate also has come into engagement with the shoe after which the operator is informed by glancing at the plate 26 whether or not the tip seam is located at the right distance from the end of the last for the particular shoe which he is operating upon. hen a different style or size of shoe is to be pulled over, the operator sets the plates 25, 26 to the new position with reference to the pointer 23 by means of the adjusting screw 24.

Having explained the nature of this invention and described a pref-erred construction embodying the same, I claim as new and desire to secure by Letters Patent of the United States:

1. In a pulling-over machine, a shoe tip measuring device comprising a member for engaging the toe end of the shoe in substantially the median line of the shoe, and a member for overlying the tip of the shoe, said latter member being supported in advance of the tip at one side of the median line of the shoe and extending around substantially to said line in a course that leaves the middle portion of the toe uncovered.

2. In a pulling-over machine, a tip measuring device comprising a bar arranged to extend across and in front of the shoe, a toe abutment located on the bar and a measuring plate supported on the bar at one side of the abutment and having a free end portion curved outwardly and backwardly and then inwardly to engage the tip seam near the median line of the shoe without covering the middle portionof the shoe.

8. In a pulling-over machine, a tip measuring device comprising a support, a centrally located toe abutment, and a laterally located measuring plate on the support having a shoe engaging portion deflected laterally backwardly and inwardly into position to cooperate with the middle portion of the tip seam.

4. In a pulling-over machine, a tip measuring device comprising members for engaging the toe end of the shoe and for overlying the tip of the shoe, said members being held in predetermined angular relation to each other and supported for limited angular movement together, and a spring arranged to hold said members in position for that member which overlies the tip to engage the shoe first and permitting said members to turn together until the toe end engaging member has also contacted wit-h the shoe.

5. In a pulling-over machine, a tip measuring device comprising the measuring plate 25 having marked thereon a graduated scale, a pointer cooperating with said marked plate, and a sickleshaped plate 26 extending from the plate 25 around the toe into position to overlie the middle portion of the tip seam for the purpose described.

(3. In a pulling-over machine a tip measurer comprising a plate mounted to extend rearwardly along the shoe at one side of the median line of the shoe and bent laterally at its rear to engage the tip seam substantially at the median line, all for the purpose described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
